Thanks for letting us know - I'm sorry to hear the issues are still persisting.
I've checked the back end of your services for you again and we are still unable to see any issues. Would you please try setting up something called a broadband quality monitor and post the link to the graph here so we can monitor your broadband performance in a different light? You'll need to have the graph running for at least 24 hours before we can get a clear picture of how your broadband service is behaving.
I've arranged a visit for you now - we can't confirm the appointment time slots publicly for security reasons, however to view your appointment time slot, please sign into your My Virgin Media account. The appointment time slot can also be rearranged from there if needed.
Let us know how the appointment goes and if you need anything else from us!
